Your Partner for the Implementation of your Visions

The requirements for modern production in constantly changing value chains are becoming increasingly complex. New materials, energy and resource conservation, and digitalization are just a few of the drivers that are forcing producers to constantly re-evaluate and optimize their processes. This requires the development of new processes, technologies, and materials, entirely new product ranges, or efficient process combinations. We, as an experienced machine and system supplier, are available as your partner for joint new developments and test series. Thanks to our strong networking with universities, and research institutes, suppliers, and partners from industry and commerce, and our in-house engineering expertise, we can pursue ideas and approaches together with you, investigate them and develop them through to prototyping and readiness for use.

Workpieces of all dimensions

The NSH Group is a system provider for all requirements in the field of metalworking processes. This includes solutions for an extremely wide range of workpiece dimensions. With our different sizes and machine concepts, we can securely clamp components of diverse sizes, geometries, and weights, as well as to machine them multidimensionally and multifunctionally. The spectrum ranges from filigree gear wheels or bearing sleeves of a few centimeters and grams to 9-meter-long shaft or steel parts weighing several tons, such as hydraulic components, large crankshafts, columns, and other heavy-duty parts. In addition, we can reliably machine disk-shaped workpieces, as well as rotationally symmetrical shaft parts, and free-forms. With our specialized machines we can to machine workpieces with more unusual shapes such as railway wheels in installed condition, gas bottle necks, and brake disks.

Workpieces of all materials

The NSH Group stands for efficiency and versatility in the machining of your workpieces - also in the range of machinable materials. With our extensive portfolio of machines and technologies, we provide economical processes for the machining of almost all machinable materials. The spectrum ranges from plastics or aluminum, simple or hardened steels, cast iron, and alloys, to high-strength materials, and special or super alloys such as titanium, Inconel 718, or Rene 41, and Rene 65. Quality and surface finish are always our top priority for both simple and complex materials. Processes and machine configuration are always optimized to ensure the best results.

Workpieces of all Industries

The NSH Group stands ready as a partner for customers in all branches of industry. With our broad experience in the field of machine tools and specialized machines for industrial production, we process your specific workpieces from all sectors in a reliable manner. These include workpieces from the mobility sectors of railway and metro, such as wheelsets, and axles; aerospace, such as turbine, and landing leg components; and the automotive sector, both for classic components such as chassis parts, conventional engine, and transmission components, and for parts of alternative drives for e-mobility or the hydrogen sector. In addition to the mobility-oriented industries, we are also a strong partner for all applications of classical mechanical engineering and engineering, be it for parts and contract manufactures, producers in the field of process engineering, manufacturers of equipment for the oil and gas industry, as well as energy production from renewable sources such as wind and hydro power.
